Application filed March 5, 1918. Serial No. 220,422.

To all whom it may concern:

Be it known that we, RICHARD G. LEDIG, and ROBERT C. Laure, both citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, and NIKOLAUS Gnnson, a subject of the Emperor of Austria, having resided in the United States one year last past and having declared my intentions of becoming a citizen thereof, residing in the city sylvania, have invented a new and useful Electric Heating and Lighting Apparatus,

of which the following is a specification.

Dur invention relates to an electro heating and lighting apparatus, the same consisting of a casing having therein an electric lamp or a plurality of electric lamps, means for energizing said lamp or lamps, said casing being adapted to be placed in various positions and provided with appurtenances whereby it may be coupled with another casing or a number of casings equippedwith an electric lamp or a number of electric lamps so as to produce combinations of the casings which may be placed in various positions relative to the requirements of use.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a perspective view of an electric heating and lighting apparatus embodying our invention.

Fig. 2 represents a longitudinal section of a portion thereof.

Fig. 3 represents a side elevation of a detached portion thereof on an enlarged scale.

Fig. 4 represents a side elevation of the apparatus showing the casing thereof in an inclined position.

Figs. 5 and 6 represent side elevations of difierent combinations that may be produced by pluralities of the apparatus.

Other combinations may be formed some of which are shown in the application for Letters Patent filed by Richard G. and Robart (I. Ledig, on the 18th day of January, In the present which form case, similar numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings 1 designates a casing metal or other material which is closed on its sides, ends and bottom, and open at what may be termed the front. Within said casing is the chamber 2 which is formed of metal or other suitable material, and containing electric lamps 3 which are properly sustained in said casing and being in an electric circuit by the conductor 4: which is connected properly with the sockets 5 of said lamps, contact points being also employed on said sockets and lamps to energize the latter, as well known in electric lamps.

The chamber 2 is provided with a reflecting surface and is closed on its sides and bottom, and open at what may be termed its front to accord with the open front of the casing 1, so; as to adapt the resultant heat and light of the lamps to be deflected outwardly from the chamber to a place of service.

The walls of the chamber 2 are separated from the walls of the casing 1 forming the space 6 which comprises an air chamber, whereby the exterior casing is kept in comparatively cool condition and so not liable to burn any one touching said casing.

7 designates legs which are adapted to sustain the casing with its contents as in Fig. 1, said legs having therein longitudinally-extending slots 8 through which pass the screws 9, the latter being adapted to enter openings .n the sides of the casmg, thus adapting the latter to be adjusted in height or placed in various positions as shown in other figures to be hereinafter stated.

The lower ends of the pairs of legs 7 have formed of suitable pivotally connected therewith the bars 10 feet providing broad bases for the legs for steadily supporting the same and assisting to prevent the legs from spreading at the bottom, while the portions of the legs above said bars may be brought together or separated for various purposes requiring the same, as shown in different figures of the drawings, it being seen that a single screw 9 may be passed through the slots of the legs as in Figs. 1, 2, and a,

or through the slot of each member of a pair of legs, as in Figs. 5 and 6 so as to adapt the legs to support a casing ora number of casings according to the posltlon of a casing, or the positions of a number of casings, it being evident that a casmg may be faced upwardly or downwardly, 1n hor1- zontal position, or in inclined position, the latter being shown in Fig. 4.

Pivotally connected with a wall of a casing are the bars 11 which may be emloyed to connect another casing or a numer of casings side by side, or one above the other, as in the prior application for the patent hereinbefore referred to.

In order to connectpne or more casings in an articulated inanner whereby a plurality of casings may be assembled right lined as in Fig. 3, or to produce a pyramidal form as in Fig. 5, or inverted from'the latter as in Fig. 6, we employ the crossed bars 12 which are connected by the pivots 13 as lazytong members, and formed with longitudinally extending slots 14 through whlch are passed the screws 15, the latter being adapted to enter the openings 16 in a side of the casing, see Fig. 4, said openings 16 previously receiving the screws 9 of the legs 7, one pairof the latter having been removed, a single pair of legs on one end of a casing and a pair of cross bars'13 on the other end thereof being employed when casings are to be coupled with each other by said cross bars, ,forms of which are shown in Figs. 5 and 6. The legs may be turned so as to occupy positions above a casing so as to act as a hanger for suspending the latter therefrom when so required.

The cross bars have been removed from Fig. 4 as the casing is in inclined position disconnected from other casings and a single pair of legs 7 supports the casing in said position.

It is evident that the cross bars may be opened or closed to a greater or less extent accordin to the right-lined or angular positions t at coupled casings assume relatively to each other.

Additional electric conductors 17 are provided they having connections with the casings so that the current can be communicated to the lamps of the different casings.

It will be seen that the heat and light from the lamps may be used for therapeutic purposes of baking an afiiicted part of a human body by subjecting the same to the light and heat, and th found beneficial for various treatments in hospitals by physicians or by ersonal use.

Again, the apparatus is serviceable for light alone, or for heat alone, and it may be employed for drying fruits and other mee a paratus will be neeaass terial and objects, for heating and warming food, and other purposes to its use we do not limit ourselves.

The cross bars of the coupling are pivotally connected nearer one end than the other so as to provide long or short throws of the bars to increase or reduce the distance be tween adjacent casings relative to different angles that the latter may be set when coupled one with the other.

he connections of the conductors 4 and '17 are removable from the casing to admit generally, and so Having thus described our invention what we claim as new and desire to secure by Letters Patent, is v 1. In an apparatus of the character stated, a casing, an electric lamp therein, means on said casing for the connection therewith of an electric conductor for said lamp, a pair of legs, the members of which are pivotally connected and have therein longitudinally extending slots, screws adapted to be passed through said slots into the wall of said casing, and a device adapted to couple said casing with an adjacent casing of substantially the same character and support it in various positions on the latter, said device consisting of slotted cross bars which are pivotally connected, and screws adapted to be passed through the slots, of the bar into the wall of the casing.

2. A casing, a pair of legs, the members of which are pivotally connected and have therein longitudinally extending slots, screws adapted to be passed through said slots into the wall of said casing and a device adapted to flexibly couple said casing angularly wlth an adjacent casing, said device consistmg of slotted cross bars which are pivotally connected, and screws adapted to be passed through said slots of said bars into the wall of the casing.
